Fault handover as a traceable sequence of tasks

Erlangen. The project Understandable fault handover in the control room is completed in the scenario. Its research report Designing fault handovers to be traceable starts from a familiar problem: at handover, the origin and age of a message are often missing.

The report describes the handover as a sequence of tasks and asks how an interface can make incomplete state visible without suggesting a certainty to act that does not exist. Two interface variants are compared in a cognitive walkthrough based on workflow cards. The focus is on the visibility of critical information and on documented risks of misinterpretation.

No real study with participants took place. The observations in the report are illustrative. The report is a document; its full text is planned as an HTML reading text and is not scientific evidence.
